BOTTLE-NECK.

'SPECIFICATION forming part of Letters Patent No. 523,728, dated .Tuly 31,1894. 4Application tiled December 7, 1893. Serial No. 493|012- (N0 mdeL) To aZZ whom tm/wy concern.:

Be it known that we, LEONARD A. PELLs and LOUIS STEINER, both of Brooklyn, in the county of Kings and State of New York, have inventeda new and Improved Bottle-Neck, of which the following is a full, clear, and exact description.

Our invention relates to improvements in blottles and particularly to the necks of bott es.

The object of our invention is to produce a bottle neck with a valve therein, the neck and valve being arranged in such a manner that liquid may be poured' freelyl from the bottle, but also in such manner that no liquid can be forced into the bottle; in this Way the fraudulent refilling of labeled bottles is prevented.

To this end our invention consists of a bottle neck, the construction of which will be hereinafter described and claimed. l

Reference is to be had to the accompanying drawings, forming a part of this specication, in which similar figures of reference indicate corresponding parts inall the views.

Figure 1 is a longitudinal section,-on the line 1-1 of Fig. 2, of the bottle neck embodying our invention. Fig. 2 is a sectional plan' on the line 2-2 of Fig. 1 and Fig. 3 is a broken perspective view of the bottle neck with parts in section.

The bottle neck 10 may be of any usual exterior shape, and may beformed on any kind of bottle body. The neck has inserted in it a shell or bushing 11, which preferably abuts at its inner2end with a shoulder l0 in thev neck, and the shell is left open in the middle to form a valve chamber 12 and has, at its lower end, a collar 13 in which is a bushing 14, this being placed centrallyandforming a bore through which the liquid may be poured. If desired the bushing and collar may be made in a single piece. The bushing 14. projects outward above the collar, forming aseat for the flat valve 15, which is adapted to close tightly over the bushing or seat, and isat one end hinged to a clip 16 on a washer17 which encircles the valve seat, and the valve is connected with the clip 16 by a spring band 18 which embraces the valve, lying in a groove in its edge. This bandis preferably of rubber, as the rubber is proof against corrosion,

but a spring may be used instead with the the bottle is tipped up to pour liquid fromit,

the valve swings outward before the outflow ing liquid, Ypermitting the liquid to pass, but if the bottle is empty, or substantially so, the valve will close, even though the bottle be held with its neck lower than its body.

The valve 15 has projecting from its free edge a guide'inger or stem 20, which swings in the slotted curved guide 21 projecting upward from one edge of the washer 17. It will be understood, however, thatV the guide and the clip 16 may be formed integral with the collar 13, if desired.

The upper end of the shell 11 is closed by a plug 22, which is provided with a central bore 23 through which the liquid may be y 24 may be inserted to close the bottle. The

plug 22 has a reduced lower end 25 in which.

are side ports 26 leading to'longitudinal ports 27, which connect with the bore 23, and thus acircuitous course is provided for the outflowing liquid which, however, will not impede its flow, but the construction of the 'plug and ports prevents any instrument from being inserted to tamper Withthe valve 15.

It will be of course understood that the' valve attachment is inserted after the bottle is filled, and is placed in position so that it cannotbe removed without breaking the bottle.

Having thus described our invention, we claim as new and desire to secure by Letters Patentv Y 1. The combination,with the bottle neck, of a collar held in the neck and provided with a seat on its outer side, a fiat valve supported above the seat and adapted to close against the same, and a'stopper plug in the outer end of the neck, the plug having a central bore extending partially through it, and side ports connecting with the bore, substantially as described.

2. The combination, with the bottle neck, of

too

a collar inthe neck having a raised valve seat on its outerside, a flat spring-pressed valve held against the seat, a guide for the valve, and a plug held in the outer end ofthe having a spring connection with the clip and a guide stem to run in the curved guide, and 15 a plug in the outer end of the shell, the plug having at its outer end a stopper bore, its inner end reduced and side ports entering 'olie reduced end and connecting with the bore, substantially as described.
